The lawsuit has been filed in the U.S. District Court for the Southern
District of New York on behalf of all those who purchased Flex
securities between November 6, 2017 and June 12, 2018 (the "Class
Period"). The case, Rumaldo v. Flex Pharma, Inc., No. 18-cv-05493
was filed on June 19, 2018, and has been assigned to Judge Vernon Speede
Broderick.

The lawsuit focuses on whether the Company and its executives violated
federal securities laws by overstating the viability and approval
prospects for its product candidate FLX-787 for the treatment of ALS and
CMT.

Specifically, on June 13, 2018, the Company announced that it had plans
to halt two ongoing Phase 2 clinical trials for FLX-787, the Company's
treatment for amyotrophic lateral sclerosis, citing oral tolerability
concerns observed in both studies. Flex further announced that the
Company would restructure its organization to reduce costs, including
reducing its workforce by approximately 60%, and that Flex's Board was
exploring "strategic alternatives, including the potential sale or
merger of the company."

On this news, Flex's share price fell from $4.18 at close on June 12,
2018 to $1.04 on June 13, 2018—a $3.14 or 75.12% drop, causing harm to
investors.

The court-appointed lead plaintiff is the investor with the largest
financial interest in the relief sought by the class who is adequate and
typical of class members who directs and oversees the litigation on
behalf of the putative class. Any member of the putative class may move
the Court to serve as lead plaintiff through counsel of their choice, or
may choose to do nothing and remain an absent class member. Your ability
to share in any recovery is not affected by the decision to serve as a
lead plaintiff or not.
